NBA director of scouting Ryan Blake knows almost all things when it comes to the draft, but he ran into something he hadn't considered when he arrived in Chicago for the combine Wednesday.

Blake was prepping for a TV show appearance when the producer called to ask for B-roll of the draft's potential sleepers. His mind started swirling through five, 10, then 20 different players.

"I didn't know what to do, because there are so many this year," Blake said. "There are too many good players for a 60-player draft."

The top 61 prospects are here, but a number of the projected lottery picks will participate only in athletic testing and off-court interviews. That leaves the door open for late first-round picks and second-rounders to show their on-court wares to the congregation of NBA executives.

It should work out perfectly for the Warriors, who own the Nos. 30 and 35 picks and need a backup big man, because many of the players with the most to gain or lose at the combine fit those credentials.

"Look at all of these power forwards. There are going to be a number of options for that backup big man," Blake said. "There are going to be good power forwards still there at 30 and 35, and you can take your pick which kind of big man you want."

If the Warriors don't use their No. 7 pick on a big man or trade the pick for an experienced player, Blake said they'll have no problem finding a quality power forward or center later in the draft. The Warriors also have the No. 52 pick, which they bought from Atlanta at the trade deadline.

There's Meyers Leonard, a 7-foot, 245-pound sophomore center from Illinois, who has a nice mix of size and athleticism. Depending on whom you ask, Leonard could be a lottery pick or could be left on the board when the Warriors draft later.

"I think he's going to prove to be better than some people think," Blake said. "I worry a little bit about his confidence, because he kind of roller-coastered some. I want him to come into the combine and show what he can do, because he can shoot the ball and can really run."

Then, there's Andrew Nicholson, a 6-9, 225-pound senior who led St. Bonaventure to its first NCAA Tournament berth since 2000. When he turned down a spot at the Portsmouth Invitational, it might have been an indicator that Nicholson no longer could be considered a sleeper.

"I really like this kid," Blake said. "He is versatile. He's big. He can shoot it from outside. He has a great motor and great hands. I think he's a first-round talent, but there are so many power forwards in the draft that he might slip."

And don't forget Fab Melo, a 7-foot, 255-pound sophomore, who was suspended for Syracuse's postseason run. He could develop into a difference-making rim protector.

"He's a little bit of an enigma, but he's a guy with size and ability," Blake said. "He'll always block shots. He's a little bit of a risk, because we don't know what motivates him."

Blake also mentioned Royce White from Iowa State, Festus Ezeli from Vanderbilt and Kevin Jones from West Virginia. Then he talked about Drew Gordon of New Mexico and Mitty High, Kyle O'Quinn from Norfolk State and JaMychal Green from Alabama. Finally, he got around to Mike Scott from Virginia, Miles Plumlee from Duke and Kevin Murphy from Tennessee Tech.

Then ...

"See, that's what I'm talking about," Blake said. "I think this is one of our deepest drafts. There are going to be good NBA rotation players drafted in the second round and guys who aren't drafted at all that make rosters."
